Try this out. 1. Backup stuff you need/want 2. Factory reset 3. Check for update I had 7.1.1 for a long while now.
Mine is brilliant, one of the best tablets around. Good screen, good battery life, fast enough. The form factor is ergonomic for watching movies, typing and reading books.
The one I had wouldn’t. It was stuck on 6 and no amount of manual attempts would budge it. Maybe things have changed in the ten days or so since I returned it.
I have the original version which is still going strong after 3 years. No more updates, but have had no problems at all.
This will update OTA to android version 7.1.1,may need to do a manual update search to trigger update.Great tablet,fairly quick good screen and speakers.Battery ranges from good to great timewise and charges quickly,best sticking to the supplied charger though.Got mine for £200 from Argos using a quidco cashback,bargain.
